Topic 1/2: Competitive Programming—OhMyZSH

Speaker: Tim-Hinnerk Heuer

A short introduction to becoming effective with OhMyZSH with a focus on competitive programming with C++. This will be free-form, so contributions are welcome. I’ll show you how you can become effective with CP on websites such as HackerRank, LeetCode and CodeChef using nothing but the shell, Vim, and the websites. You’ll need to be very proficient with a programming language for competitive programming. I would recommend C++ and Python as the two languages of choice, but you can use a lot of languages such as JavaScript, Java, and many more.

Hopefully we can all learn something in this session and most importantly—have fun.

Topic 2/2: Gemini

Speaker: Giovanni Moretti

Gemini is a new internet protocol which:

– Is heavier than gopher
– Is lighter than the web
– Will not replace either
– Strives for maximum power to weight ratio
– Takes user privacy very seriously

Topic 1/2: rsync

Speaker: Tom Ryder

You’d think copying files between two different machines would be a relatively simple task, but it’s fraught with all sorts of subtlety and wastefulness. The rsync tool changed everything—fast, efficient, accurate file copies, right down to preserving file permissions, compressed transfer, and differential transfer—transferring only changed data. Tom will provide an introduction to command‐line rsync and a treatment of a couple of applications using it: the Grsync GUI, and the Dirvish backup system.

Topic 2/2: Quasar

Speaker: William Bell

William will demonstrate projects with the Quasar VueJS JavaScript
framework, and how to use it with Docker.

PASSWORD MANAGERS

Speaker: Tom Ryder

Re-using the same passwords on multiple sites causes a lot of security problems, but humans aren’t good at remembering a large number of passwords. Part of a good solution is a secure password manager. Tom will demonstrate a few Linux-friendly options, including his own favourite, password-store.

AV1

Speaker: Nick Skarott

AV1 is another in a line of freely available patent free video codecs. But despite the fact other free codecs exist like VP9, adoption of this codec outside of YouTube is next-to-non existent. What makes AV1 different to the point that has streaming giants like Netflix and Twitch to all the big hardware vendors like Intel, AMD and Nvidia joining the Alliance for Open Media (AOMedia)?
